Spatial Knowledge-Infused Hierarchical Learning: An Application in Flood Mapping on Earth Imagery

1 code implementation12 Dec 2023 Zelin Xu, Tingsong Xiao, Wenchong He, Yu Wang, Zhe Jiang

The problem is challenging due to the sparse and noisy input labels, spatial uncertainty within the label inference process, and high computational costs associated with a large number of sample locations.

Manifold-Aware Self-Training for Unsupervised Domain Adaptation on Regressing 6D Object Pose

1 code implementation18 May 2023 Yichen Zhang, Jiehong Lin, Ke Chen, Zelin Xu, YaoWei Wang, Kui Jia

Domain gap between synthetic and real data in visual regression (e. g. 6D pose estimation) is bridged in this paper via global feature alignment and local refinement on the coarse classification of discretized anchor classes in target space, which imposes a piece-wise target manifold regularization into domain-invariant representation learning.

BiCo-Net: Regress Globally, Match Locally for Robust 6D Pose Estimation

1 code implementation7 May 2022 Zelin Xu, Yichen Zhang, Ke Chen, Kui Jia

Inspired by the success of point-pair features, the goal of this paper is to recover the 6D pose of an object instance segmented from RGB-D images by locally matching pairs of oriented points between the model and camera space.

Classification of Single-View Object Point Clouds

no code implementations18 Dec 2020 Zelin Xu, Ke Chen, KangJun Liu, Changxing Ding, YaoWei Wang, Kui Jia

By adapting existing ModelNet40 and ScanNet datasets to the single-view, partial setting, experiment results can verify the necessity of object pose estimation and superiority of our PAPNet to existing classifiers.

W-PoseNet: Dense Correspondence Regularized Pixel Pair Pose Regression

no code implementations26 Dec 2019 Zelin Xu, Ke Chen, Kui Jia

Solving 6D pose estimation is non-trivial to cope with intrinsic appearance and shape variation and severe inter-object occlusion, and is made more challenging in light of extrinsic large illumination changes and low quality of the acquired data under an uncontrolled environment.
